hi,
as usual, i might add ;)
i'm trying to integrate lcov at least a bit. i've gotten this far, and
it completely doesn't work:
dnl LCOV
dnl ====
enable_lcov=no
AC_ARG_ENABLE([lcov],
[AS_HELP_STRING([--enable-lcov[=output-directory]], [enable coverage data
generation using LCOV (GCC only) [default=no]])],
[enable_lcov=$enableval])
AS_IF([test "x$enable_lcov" != "xno"],
AX_CFLAGS_GCC_OPTION(-fprofile-arcs -ftest-coverage)
AS_IF([test "x$enable_lcov" = "xyes"],
[lcov_output_directory="coverage-report"],
[lcov_output_directory="$enable_lcov"]
)
AC_SUBST(lcov_output_directory)
)
what i'm after is --enable-lcov=(no|yes|directory), with no being the
default (which doesn't affect anything).
"yes" and <directory> should add -fprofile-arcs -ftest-coverage to
CFLAGS, and give me a variable that is usable in Makefile.am; in case
of "yes", some default string, in other cases the argument string.
the Makefile.am bit is like this:
coverage-reset:
find . -type f -name '*.gcda' -exec rm -f '{}' ';'
lcov --directory . --zerocounters
coverage:
rm -rf coverage ${lcov_output_directory}
-mkdir -p coverage ${lcov_output_directory}
lcov --compat-libtool --capture --directory . --output-file
coverage/coverage.info
genhtml --output-directory ${lcov_output_directory}
coverage/coverage.info
.PHONY: coverage-reset coverage
(open to any alternative ways of achieving this, too)
fyi this is a front-end for gcc-generated coverage data, and produces
reports like http://dawn.dev.hu/~ice/tmp/coverage-report/ this. quite
useful, but it would be more useful if such reports could be produced
by simply enabling a switch (since what i really need is long-ish term
usage stats by people who use more eye candy than i do).
